● The terminal box can only be used for double cabling for
power connection.
● The double cabling connection diagram shows a possible
circuit. When planning the double cabling, please note the
applicable installation regulations at the installation site of
the machine.
● Temperature sensor 1TPx (SNM.150.DK*) has to be con‐
nected to the controller for thermal protection of the motor.
Temperature sensor 2TPx (KTY84*) is only available for ex‐
ternal motor temperature monitoring.
● Fuses F1 (NH…) protecting the wires from overload in case
of cable break are dimensioned according to the current car‐
rying capacity of the respective line cross section.
● The fuses should be installed in the control cabinet as close
as possible to the power output of the controller.
● The shield of the power cables should be connected to the
switch cabinet on a large scale!
● Cable pairs have to be connected correctly to series terminal
strips or to the terminal studs of the controllers and have to
comply with the relevant safety requirements.
● Finished power cables are not available for double cabling.
To install the fuses, standard Rexroth power cables have to
be opened and cut to the appropriate length on site.
Power cable connection at the ter‐
minal box
The output direction of the power cable is defined in the type code of the mo‐
tor. The terminal box is mounted to the motor according to this output direc‐
tion which cannot be changed at a later point. Connecting the power cable to
the terminal box requires the following steps:
1.
Open the terminal box cover.
